Exhibit 99.1

Disclosure about Oil and Gas Producing Activities  Accounting Standards Codification 932, Extractive Activities  Oil and Gas (unaudited)

The following disclosures have been prepared in accordance with FASB Accounting Standards Codification 932, Extractive Activities
 Oil and Gas. In December 2009, Husky adopted revised oil and gas reserve estimation and disclosure requirements that conformed the definition of proved reserves to the SEC Modernization of Oil and Gas Reporting rules, issued by the SEC
in 2008. An accounting standards update revised the definition of proved oil and gas reserves to require that the average, first-day-of-the-month price during the 12-month period before the end of the year rather than the year-end price, must be
used when estimating whether reserve quantities are economic to produce. This same 12-month average price is also used in calculating the aggregate amount of (and changes in) future cash inflows related to the standardized measure of discounted
future net cash flows. The rules also allow for the use of reliable technologies to estimate proved oil, natural-gas, and natural-gas liquids (NGLs) reserves if those technologies have been demonstrated to result in reliable conclusions about
reserve volumes.

The unaudited supplemental information on oil and gas exploration and production activities for 2012, 2011,
and 2010 has been presented in accordance with the revised reserve estimation and disclosure rules, which were not applied retrospectively.

Husky completed a transition to International Financial Reporting Standards in 2011 and all 2012, 2011 and 2010 financial information has been prepared using IFRS as issued by the International Accounting
Standards Board.

Oil and Gas Reserves

Proved oil and gas reserves are those quantities of oil and gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible from a
given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulations.

Proved developed oil and gas reserves are proved reserves that can be expected to be recovered:(i) through existing wells with existing equipment and operating methods or in which the cost of the required
equipment is relatively minor compared to the cost of a new well; and (ii) through installed extraction equipment and infrastructure operational at the time of the reserves estimate if the extraction is by means not involving a well.

Proved undeveloped oil and gas reserves are proved reserves that are expected to be recovered from new wells on undrilled
acreage, or from existing wells where a relatively major expenditure is required for recompletion.

Canadian provincial
royalties are determined based on a graduated percentage scale, which varies with prices and production volumes. Canadian reserves, as presented on a net basis, assume prices and royalty rates in existence at the time the estimates were made, and
Huskys estimate of future production volumes. Future fluctuations in prices, production rates, or changes in political or regulatory environments could cause Huskys share of future production from Canadian reserves to be materially
different from that presented.

Subsequent to December 31, 2012, no major discovery or other favourable or adverse event
is believed to have caused a material change in the estimates of developed or undeveloped reserves as of that date.

Note that
the numbers in each column of the tables throughout this exhibit may not add due to rounding.

|(1) | Net reserves are the Companys lesser royalty, overriding royalty and working interest share of the gross remaining reserves, after deduction of
any crown, freehold and overriding royalties. Such royalties are subject to change by legislation or regulation and can also vary depending on production rates, selling prices and timing of initial production.
|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(2) | Reserves are the estimated remaining quantities of oil and gas and related substances anticipated to be economically producible, as of a given date, by
application of development projects to known accumulations.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(3) | Proved oil and gas reserves are those quantities of oil and gas which, by analysis of geoscience and engineering data, can be estimated with reasonable
certainty to be economically producible from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulations.
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(4) | Proved developed oil and gas reserves are proved reserves that can be expected to be recovered: (i) through existing wells with existing equipment
and operating methods or in which the cost of the required equipment is relatively minor compared to the cost of a new well; and (ii) through installed extraction equipment and infrastructure operational at the time of the reserves estimate if
the extraction is by means not involving a well. Proved undeveloped oil and gas reserves are proved reserves that are expected to be recovered from new wells on undrilled acreage, or from existing wells where a relatively major expenditure is
required for recompletion.

Standardized Measure of
Discounted Future Net Cash Flows Relating to Proved Oil and Gas Reserves (unaudited)

The following information has been
developed utilizing procedures prescribed by FASB Accounting Standards Codification 932, Extractive Activities  Oil and Gas and based on crude oil and natural gas reserve and production volumes estimated by the Companys
reserves evaluation staff. It may be useful for certain comparison purposes, but should not be solely relied upon in evaluating Husky or its performance. Further, information contained in the following table should not be considered as
representative of realistic assessments of future cash flows, nor should the standardized measure of discounted future net cash flows be viewed as representative of the current value of Huskys reserves.

The future cash flows presented below are based on average sales prices and cost rates, and statutory income tax rates in existence as of
the date of the projections. It is expected that material revisions to some estimates of crude oil and natural gas reserves may occur in the future, development and production of the reserves may occur in periods other than those assumed, and actual
prices realized and costs incurred may vary significantly from those used.

Management does not rely upon the following
information in making investment and operating decisions. Such decisions are based upon a wide range of factors, including estimates of probable as well as proved reserves, and varying price and cost assumptions considered more representative of a
range of possible economic conditions that may be anticipated.

The computation of the standardized measure of discounted
future net cash flows relating to proved oil and gas reserves at December 31, 2012 was based on the NYMEX 2012 average natural gas cash market price of U.S. $2.78/mmbtu (2011 average  U.S. $4.15/mmbtu; 2010 average  U.S.
$4.45/mmbtu) and on crude oil prices computed with reference to the 2012 average WTI spot price of U.S. $95.38/bbl (2011 average  U.S. $95.95/bbl; 2010 average  U.S. $79.43/bbl).
